Error in files for RADIOSS RDE 1400 - Truck with flexible body

Crashphys

I ran the attached demo from taken straight from the directory and got the following error:

ERROR ID : 629
** ERROR WITH EIGENPROBLEM DEFINITION AND SPMD CALCULATIONS
DESCRIPTION :
-- EIG ID : 1
-- EIG TITLE : Eig 1
NUMBER OF NODES FOR EIGENPROBLEMS MUST BE EQUAL TO THE TOTAL NUMBER OF NODES
NUMBER OF NODES FOR EIGENPROBLEM 14354 : 24731
TOTAL NUMBER OF NODES : 0

Can someone explain what is wrong?

Hi,

The eigenvalue solver only works with SMP (-nt) parallelization and not SPMD (-np).

However, even when I try to run the model with -nt it does not run. Using flexible body in a simulation has many limitations and does not work with many new Radioss options.

I would recommend not using this method. For longer simulation times you can use regular mass scaling (/DT/NODA/CST) or Advanced Mass scaling /DT/AMS to increase the time step and reduce the simulation time.

Thanks,

Andy

HI,

I'm trying to find anything I can that can reduce simulation time further. DT/NODA/CST is effective, however AMS has proven to be incredibly unstable, and the multi domain technique does not work for my application. Is there any way to perform any other model order reduction?
